WMS_CACHE_QUERY_TYPE_FLAGS

The WMS_CACHE_QUERY_TYPE_FLAGS enumeration type indicates the purpose of a call to the QueryCache method on the IWMSCacheProxy interface.

Syntax

  typedef enum WMS_CACHE_QUERY_TYPE_FLAGS{
  
  WMS_CACHE_QUERY_OPEN  = 0x1,
  
  WMS_CACHE_QUERY_GET_CONTENT_INFO  = 0x2,
  
  WMS_CACHE_QUERY_CACHE_EVENT  = 0x4,
  
  WMS_CACHE_QUERY_REVERSE_PROXY  = 0x8,
  
  WMS_CACHE_QUERY_LOCAL_EVENT  = 0x10
  
  };

Members

WMS_CACHE_QUERY_OPEN

A request for content from the server was made by a downstream client.

WMS_CACHE_QUERY_GET_CONTENT_INFO

When a downstream cache proxy device requests information about content that has been cached on a Windows Media server, the cache plug-in must send information about the content to the downstream device. The information is obtained by the calling the GetContentInformation method on the IWMSCacheProxyServer interface.

WMS_CACHE_QUERY_CACHE_EVENT

A downstream cache proxy device propagated a remote cache event.

WMS_CACHE_QUERY_REVERSE_PROXY

The server is configured as a reverse proxy. A cache proxy plug-in can check this flag to determine whether it must map client requests to an upstream server farm. Typically, only cache proxy plug-ins that are designed to support reverse proxy must check this flag.

WMS_CACHE_QUERY_LOCAL_EVENT

The server sets this flag if it is the first in a chain of distribution servers and must send a log, file open, or file close event to an upstream server. Because cache proxy plug-ins are responsible for propagating events, your plug-in can check this flag to determine an appropriate action. For more information about the events that an upstream server can subscribe to, see the WMS_CACHE_REMOTE_EVENT_FLAGS enumeration type.

Requirements
